In Stash comments that use the triple backtick to create code blocks, XML is being flattened our to a single line.

Example of issue:

Some plain text...
```
<parent>
  <child>content</child>
</parent>
```

Is being rendered as...

Some plain text...
<parent>  <child>content</child></parent>

However, if you don't have the line of plaintext directly above the code block, it seems to render just fine.
